GAUGE COCK.

Specification of Letters Patent.

Patented Apr. 11, 1922.

Application filed. January 19, 1920. Serial No. 352,313.

To all 1072-0722-7225 may concern Be it known that I, HENRY Kiiiiiirr, a citizen or" the United States, and resident of Gladstone, in the county of Delta andiSt-ate of Michigan, have invented certain new and useful Improvements in Gauge Cocks; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to gauge cocks and more particularly to thespecific parts constituting the valve and valve seat. 7

p m ry objector my invention consists in'providiiig a gaugecockotthis character, with a valve member so constructed and associated with the various parts of the gauge cock as to eliminate wear upon the valve and valve seat.

A more specific object resides in the provision of a valve member so constructed that proper alinement and seating of the same is assured.

A further object of my invention is to provide a separable valve unit or member associated with a one piece valve housing wherein provision is made to assemble or renew the valve unit by passing the same through the valve stem opening, which opening is of greater diameter than the head of the removable valve member. By making a provision of this character I have been able to produce a valve of minimum cost with pro vision for removing the valve unit in a simple manner.

\Vith these objects in view the invention comprehends certain details of construction and peculiar arrangement of parts such as will be described and specifically pointed out in the appended claim.

In the accompanying drawing:

Figure 1 represents a gauge cock embodying the features of my invention the same being broken away and in section to more clearly illustrate the points of the invention.

Figure is a detail sectional view taken upon the line 22 of Figure 1.

Figure 3 isa detail view of the valve mei her.

At the present time it is common custom in the construction of gauge cocks and simi lar types of valves to construct the valve member integral with or rigidly secure the same to the actuating handle. From this construction it will be seen that rotary movement of the actuating handle will cause the valve member to be revolved upon its seat,

and inasmuch as cocks of this nature are used where a high pressure is employed, it

becomes necessary to obtain a very tight closure of the valve, which causes a great triction between the valve and valve seat, and due to the rotary movement of the valve portion upon the seat, undesired wear be tween these members results. Furthermore where the valve is rigidly secured to the actuating handle or formed integral therewith it is somewhat difiicultand expensive to obtain a proper and exact alinement between the valve aiid valve seatwhereby a perfect closure is assured.

These objectionable features have been overcome in the constructioii'ot niv invention as shown in the drawing, in which a onepiece valve housing, designated by the numeral 1, is provided with extension 2, havingavalve stem opening which is threaded interiorly to receive a valve actuating stem 3, and provided extcriorly with a customary packing gland l. The opposite side of the housing 1 is providcdwith an inlet port 5,

in alinement with the valve actuating handle and adapted to receive the grooved shank 6, of a valve member 7, the same being provided with a head portion 8 adapted to form a closure for the valve seat 9 at the interior end of the inlet port 5.

The interior portion 10 of the actuating stem 3 is adapted to abut the valve head 8 and is rounded at its end, in order to eliminate friction between thesame and the valve.

By referring to Figure 1 oil. the drawings it will be seen that the threaded valve stem opening of the one piece housing is of greater diameter than the diameter of the circular head 8 ot the valve member and hence it will be readily seen that in assembling the structure this valve unit 8 can be dropped through the valve stem opening to its seat. It also shows that should the valve member wear and require repairs, the simple valve unit which is worn can readily be renewed and a new one substituted by unscrewing the cap 4. and valve stem, whereby access may be had to withdraw the valve member from the housing without dismantling any of the part or without depending upon a skilled mechanic for repairs.

From this construction it will be readily seen that as the actuating handle 3 is revolved in one direction, it will permit the valve 7 to be opened, due to the fluid pressure exerted upon the same, while manipulation of the actuating handle in the opposite direction will cause the end portion 10 to abut the valve and force the same upon its seat, and because of the abutting engagement between the end portion 10 and the valve 8, rotary movement of the actuating handle will not be transmitted to the valve, thereby eliminating any grinding wear between the valve and its seat. As the actuating handle is released or run out and the valve permitted to raise from its seat, fluid will pass through the inlet port around the grooved shank of the valve, while at the same time, the shank having a bearing in the inlet port, holds the valve in proper alinement with its seat.

lVhat is claimed is:

In a gauge cock embodying a one piece housing having an alined valve seatinginlet port and a threaded valve stem opening, the

'latter'being of greater diameter than the inlet port, the wall surroundmg the inlet port having an annular upwardly extendmg rib forming the valve seat; the combination oi a removable valve member comprising a flat head adapted to engage the inlet port seat, and a grooved shank portion having a bearing in said outlet port to hold the valve head in alinement with said seat, said shank portion being considerably longer than the diameter of said inlet port, the head being of less diameter than the valve stem opening, whereby said valve member may be passed through the opening for assemblage or renewal, and a valve stem in threaded engagement with the valve stem opening, the stem terminating with an integral finger portion provided with a rounded end, which is adapted to have a single point engagement with the fiat head of the valve to hold it upon its seat, whereby frictional engagement of the finger and head is reduced to a minimum, the valve stem element being entirely separate from member. 7

In testimony that I claim the foregoing l have hereunto set my hand at Gladstone, in the county of Delta and State of 'Michigan.
